2024-07-01Dry Mortar Mixed Plant Overall Equipment Maintenance System
1. After the completion of each work, the responsible personnel of the mixing station should clean up and maintain the project: (1) Clean up the ash accumulation inside and outside the wall of the mixing tank, the concrete residue on the discharge port, the mixing shaft and the discharge door, wash these places with water, and if necessary, put a small amount of stones and water into the mixing for a few minutes before releasing. Clean vehicle, additive tank and supply system with water. (2) Freezing season, at the end of the work, the pump, additive pump, water tank, additive tank, water, residual water and additive in the additive pipeline should be drained to prevent damage to the pump and its pipeline, and start the additive pump of the pump to run for 1-2 minutes. 2. dry mortar mixed plan weekly inspection maintenance items: (1) Whether the manual oil pump needs to be lubricated (2) Each lubrication point must be lubricated Note: The lubrication points are located at the gate shaft of the mixer, the gate shaft of the storage hopper and weighing hopper, the belt conveyor, the machine support wheel, the press wheel, the roller, the bearing, the transmission...

2024-06-28What Is the Role of the Sheet On The Wall of the Sand Dryer Cylinder?
Sand dryer is equipped with a copy plate on the wall of the cylinder body, its role is to copy the material and sprinkle it, is to increase the contact surface of the material and air flow, to improve the drying rate and promote the progress of the material, the heat carrier is generally divided into hot air, flue gas, etc., the heat carrier after the dryer, generally need a cyclone dust collector to collect the material in its body. If it is necessary to further reduce the dust content of the tail gas, it should also be discharged after the dust collector or the initial dust collector.

The Maintenance Work of Sand Dryer Cannot Be Ignored
In order to reduce the wear of sand dryer parts and improve their service life, it is necessary to regularly maintain them. Lubrication maintenance is an important task in the maintenance of sand dryers. If the lubrication work is not done well, it can accelerate the wear of equipment components, and in severe cases, serious safety accidents may occur. This shows the importance of lubrication maintenance for dryers.

2024-06-27Quartz Sand Triple Cylinder Rotary Drying Machine
An efficient and environmentally friendly Drying solution -Quartz Sand Triple Cylinder Rotary Drying Machine: Quartz sand is a natural mineral widely used in glass, ceramics, coatings and other industries. Because of its high light transmittance, high temperature resistance, corrosion resistance and other characteristics, it plays an important role in many industrial fields. However, quartz sand needs to go through many processes in the processing process, of which drying is a crucial part. How it works: Quartz Sand Triple Cylinder Rotary Drying Machine adopts advanced heat energy recovery technology to import the heated hot air into the cylinder, so that the quartz sand rolls in the cylinder and fully contacts the hot air. With the rotation of the drum, the quartz sand is constantly stirred and heated in the process of progress, so that the water gradually evaporates and is discharged by the exhaust port. At the same time, part of the exhaust gas is recovered through the thermal energy recovery system, which is used to heat fresh air, further improving the thermal efficiency. Features and advantages: High efficiency and energy saving Wide range of application High degree of automation Clean and environmental protection Application scenario: Glass industry Ceramic industry Coating...

2024-06-26What Are the Key Features of A Dry Mortar Mixed Production Line？
The main function of the dry mortar production line is to mix the dried and screened sand with cement, fly ash admixture and other materials in a certain proportion into masonry mortar, plastering mortar and floor mortar for construction, which is supplied to engineering construction in the form of packaging or bulk. According to the production capacity of the factory, the scale of the dry mortar production line is divided into tens of thousands of tons per year, mostly between 100,000 and 600,000 tons. According to the layout of dry mix mortar production line, there are tower type and two-stage type. The tower-type layout has smooth material flow, small footprint, but large structural cost. The two-stage layout increases the secondary lifting, the storage bin is mainly arranged on the ground, the equipment cost is low, and it is a more common form of application.
